For this exercise, you are going to write a recursive function that counts down to a Blastoff! Your recursive function will not actually print. It will return a String that can be printed from the main function. Each recursive call will add on to that string. In your main function, prompt the user for a starting value, then print the results. Sample Output Please enter a number to start: 5 5 4 3 2 1 Blastoff! import java.util.Scanner; public class Countdown { public static void main(String[] args) { // Start here } public static String countdown(int number) { // Base case - return Blastoff! // Recursive call } }

Sample Output
Please enter a number to start: 5 5 4 3 2 1 Blastoff!
import java.util.Scanner;
public class Countdown
{
public static void main(String[] args)
{
// Start here
}
public static String countdown(int number)
{
// Base case - return Blastoff!
// Recursive call
}
}
